If you didn't see this coming, then you clearly don't pay enough attention to the Humble Bundle. The recently announced Humble Bundle with Android 6 is halfway through its two-week run, and that means a "surprise" addition of a few more games and soundtracks.

Joining the group of Android-friendly games are McPixel, Waking Mars, and NightSky HD. NightSky has been a part of a previous bundle, so if you didn't get it then, you have a second chance at it. If you already previously bought this current bundle, you should already own these three additional games and soundtracks; otherwise, a minimum payment above the average (currently $4.70) unlocks them.
